Public relations people and top-level executives at Halliburton, one of the world's largest oilfield services companies, are likely breathing a sigh of relief after the oilfield services company found a radioactive rod that it lost last month, the Guardian reports. The seven-inch rod of americium-241/beryllium was found alongside a Texas highway some miles away from where it was being used to locate oil and gas deposits eligible for fracking.

But radioactive materials sometimes do turn up in unexpected places. In 2010, Italy experienced the worst radiological incident in its history when a shipping container arrived in the port city of Genoa with unsafe levels of radiation, WIRED reports. The source turned out to be a radioactive rod not much larger than a pencil.
